Magellanic Penguins Devour 2 Million Tons of Seafood Yearly
South American Magellanic penguins gobble down 1.5 million tons of silverside fish, squid and small, oily fish such as sprat every year. If all of the world's 1.3 million Magellanic penguins are as voracious as their Patagonian counterparts, then the black-and-white birds may be bolting down 2 million tons of...

Penguins Wear a Shield of Cold Air in Winter
Emperor penguins “wear” an invisible shield of cold air that helps to prevent body heat loss, allowing the flightless birds to survive the sub-zero temps of Antarctica, a new study finds. The report, published in the journal Biology Letters, demonstrates just how hardy the birds are. “In most birds, plumage...

Penguins Thrived in Antarctica During Little Ice Age
Penguin populations in the Ross Sea of Antarctica spiked during the short cold period called the Little Ice Age, which occurred between A.D.1500 and 1800, new research shows.
